Spontaneously, https://www.meshlab.net would come to mind. An acquaintance of mine uses this tool. I myself have nothing to do with 3D printing and can therefore not share any experiences.
I never did any heavy 3D-Printin in the short time I had access to a printer, but I always used fstl (https://github.com/fstl-app/fstl) to view stl files and Prusa Slicer as a slicer.
